i think at this point it would help the rest of us help you if you went into your computer set up in detail as well as the audio interface your useing.
plus post pics of your sound device settings in windows
AND realband AND your audio interfaces control panel if it has one.
otherwise its just "a guessing game for the rest of us".
often it comes down to how a rig is set up and its settings assuming there isnt a software bug.
and solutions are often a process of elimination.
